を嵌合できないようにするのが好ましい。 The locking cover for the mating connector falls down to the side of the adjacent connector mating part due to its own weight and blocks this, thereby preventing incorrect mating of the connector.
As described in (2), a connector cannot be fitted to an adjacent connector fitting part unless a spring is interposed between the cover and one connector fitting part to lock the cover. It is preferable to do so.
以下、上記構成を実施例を示す図面を参照して
具体的に説明する。 The above configuration will be specifically described below with reference to drawings showing examples.
第１図に本考案の電気接続部の要部の斜視図、
第２図に同上の分解斜視図を示した。
FIG. 1 is a perspective view of the main parts of the electrical connection part of the present invention.
FIG. 2 shows an exploded perspective view of the same as above.

クタ嵌合部１１2側に面して回動可能に装着され
ている。 The above is the same as the conventional one, but in the present invention, the locking cover 16 for the mating connector on the desired connector fitting portion 11 1 is rotatable so as to face the adjacent connector fitting portion 11 2 side. is installed on.
すなわち、ロツキングカバー１６は、相手コネ
クタに対する覆板１７とその支持板部１８とから
成る断面ほぼＬ形の形状を有する。 That is, the locking cover 16 has a substantially L-shaped cross section, consisting of a cover plate 17 for the mating connector and a supporting plate portion 18 thereof.

如く構成する。 Then, a coil spring 21 is wound around the pin shaft 20, and one end of the coil spring 21 is engaged with the spring receiving groove 22 of the support plate part 18, and the other end is engaged with the side wall of the connector fitting part 111 . Under normal conditions, the cover 16 is biased toward the adjacent connector fitting portion 11 2 and falls over, and the support plate portion 18 covers the fitting portion 11 2 .

図示を省略する。 Note that wiring boards such as printed circuit boards and busbar circuit boards constituting internal circuits are housed in the insulating box 10, and groups of connection terminals that are electrically connected to the wiring boards are connected to the connector fitting portions 11 1 , 11 2 . . . These may be accommodated and arranged according to known configurations,
Illustrations are omitted.

In Figure 3a, connectors 25 1 and 25 2
1 and 2 show mating connectors of connector fitting portions 11 1 and 11 2 , respectively.
ロツキングカバー１６が、前記コイルバネ２１
に付勢されて転倒し、コネクタ嵌合部１１2を覆
つているから、コネクタ２５2をコネクタ２５1よ
り先に嵌合することができない。 The locking cover 16 is attached to the coil spring 21.
The connector 25 2 cannot be fitted before the connector 25 1 because the connector 25 2 falls down and covers the connector fitting portion 11 2 .
従つて、コネクタの誤嵌合の防止と共に、嵌合
順序も規制される。 Therefore, in addition to preventing incorrect fitting of the connectors, the fitting order is also regulated.
そこで、コネクタ２５1をコネクタ嵌合部１１1

２により一次ロツクする。 Therefore, the connector 25 1 is connected to the connector fitting part 11 1
The locking arm 26 and the locking part 1
2 provides primary lock.

バー側に設けることもできる。 Next, as shown in FIGS. 3a and 3b, the locking arc 16 is pulled in the arrow direction, and the locking hole 24 of the locking arm 23 and the locking pawl 15 engage with each other, so that the cover 16 is fitted into the connector. Section 11 Lock to 1 . As a result, the protrusions 27, 27 formed on the upper part of the connector 251 are pressed down from above by the cover plate 17, so that the connector 251 is doubly locked.
Note that the protruding piece 27 is attached to the cover plate 1 of the locking cover 16.
7 may be omitted as long as the cover 16 has a structure that covers a part of the connector 25 1 , but by forming the cover 16 in a shape that aligns with the cover plate 17 or the support plate part 18 when the cover 16 is erected, incorrect fitting of the connector can be avoided. It can function as a prevention piece, and therefore the protruding piece 27 can also be provided on the cover side.
コネクタ２５1をコネクタ嵌合部１１1に完全に

妨げる。 Even if the connector 25 1 is completely fitted and locked into the connector fitting portion 11 1 , if the locking cover 16 is not locked, the cover 16 will not hold the coil spring 21 .
The elastic force causes the connector to fall over and prevent the connector 25 2 from fitting.
従つて、コネクタ２５1は必ずコネクタ嵌合部
１１1に二重ロツクされる。なお、コイルバネ２
１が介装されていない場合であつても、ロツキン
グカバー１６は自重により倒れるから、同様の効
果が達成される。 Therefore, the connector 25 1 is always double locked to the connector fitting portion 11 1 . In addition, coil spring 2
Even if the locking cover 16 is not interposed, the same effect can be achieved because the locking cover 16 will fall down due to its own weight.
このように、コネクタ２５1とそのコネクタ嵌
合部１１1をたとえばエアバツグ装置のような配
線系統のコネクタとして使用すれば、きわめて安
全確実な電気的接続を行うことができる。 In this way, if the connector 25 1 and its connector fitting portion 11 1 are used as a connector for a wiring system such as an airbag device, an extremely safe and reliable electrical connection can be achieved.

嵌合する手順である。
The work standard for connecting the connector to the electrical junction box B is to fit the connector 25 1 into the connector fitting part 11 1 and double lock it with the locking cover 16, as explained in FIGS. 3a and 3b. After that, the next step is to fit the connector 25 2 into the connector fitting portion 11 2 .
しかし、この作業準備に反して、第４図ａ，ｂ
のように、ロツキングカバー１６を手で引き起こ
し、コネクタ２５2を先に嵌合する場合も生じう
る。 However, contrary to this work preparation, Fig. 4 a, b
There may also be a case where the locking cover 16 is raised by hand and the connector 25 2 is fitted first, as shown in FIG.
この場合、第４図ｃのように、ロツキングカバ
ー１６が前述のコイルバネ２１または自重によつ

１１1の上端開口部は十分に開放されるので、第
４図ｄのように、コネクタ２５1を後で嵌合する
ことも可能である。 In this case, as shown in FIG. 4c, since the locking cover 16 is tilted toward the connector 25 2 by the coil spring 21 or its own weight, the upper end opening of the connector fitting portion 11 1 is sufficiently opened. It is also possible to mate the connector 25 1 later, as shown in FIG. 4d.
この嵌合順序は作業基準に反し、コネクタのチ
エツク回路（図示せず）の正常な機能を妨げるか

好ましい。 Since this mating order violates work standards and interferes with the proper functioning of the connector's check circuit (not shown), it is preferable to provide means to correct the incorrect mating order.
第５図は嵌合順序確認部材を備えた電気接続箱
の実施例を示す側面図である。 FIG. 5 is a side view showing an embodiment of an electrical connection box equipped with a fitting order confirmation member.
すなわち、ロツキングカバー１６とコネクタ２
５2との対向面において、コネクタ２５2の側面に
嵌合順序確認用の突起２８が設けられている。 That is, the locking cover 16 and the connector 2
A protrusion 28 for confirming the fitting order is provided on the side surface of the connector 25 2 on the surface facing the connector 5 2 .
この突起２８は、支持板部１８に当接してロツ

により、覆板１７がコネクタ２５1の突片２７ま
たはロツキングアーム２６に係合し、ストツパと
して作用するように設けられる。 This protrusion 28 abuts against the support plate part 18, causing the locking cover 16 to further incline toward the connector fitting part 111 , and by keeping the inclination position at a predetermined angle, the cover plate 17 is caused to protrude from the connector 251. It is provided to engage the piece 27 or the locking arm 26 and act as a stop.
この場合には、コネクタ２５2を先に嵌合する

嵌合部１１1への嵌合を途中で停止させるから、
コネクタ２５1および２５2の嵌合順序に誤りのあ

手順に戻すことができる。 In this case, if the connector 25 2 is fitted first, the fitting of the connector 25 1 to the connector fitting portion 11 1 will be stopped midway due to the above action.
An error in the fitting order of the connectors 25 1 and 25 2 is automatically checked during the work process, and the correct procedure can be restored.
第５図は嵌合順序確認部材としての突起２８を
コネクタ２５2側に設けた例であるが、ロツキン
グカバー１６の支持板部１８側に設けてもよい。 Although FIG. 5 shows an example in which the protrusion 28 as a fitting order confirmation member is provided on the connector 252 side, it may also be provided on the support plate portion 18 side of the locking cover 16.
第６図は第５図の改良例を示し、コネクタ２５

グカバー１６の支持板１８に突設したものであ
る。 FIG. 6 shows an improved example of FIG. 5, in which the connector 25
An engaging protrusion 29, which faces the protrusion 28 of No. 2 , is provided on the support plate 18 of the locking cover 16.

１６がロツクされる寸法にとる。 The engagement protrusion 29 is chevron-shaped and has a gentle slope 2 on the upper side.
9a, has a steep slope 29b below. The height h of the apex O of the engagement protrusion 29 from the support plate 18 is such that when the protrusion 28 comes into contact with the apex O of the engagement protrusion 29, the locking hole 24 of the locking cover 16 is connected to the connector fitting portion 11. The cover 16 is dimensioned to be engaged with the locking pawl 15 of No. 1 to lock the cover 16.

When the locking cover 16 reaches the apex O, the locking cover 16 is locked in a substantially upright state relative to the connector fitting portion 111 as described above. Therefore, the connector 25 1 cannot be fitted later.

Due to the clearance c between the locking hole 24 and the locking pawl 15, the locking cover 16 is once tilted in the direction of the arrow when the projection 28 and the apex O of the engagement projection 29 come into sliding contact, so that the locking cover 16 can be moved smoothly. be exposed.
